Which Primetime Star Presented Lauren Conrad With an Award? (PHOTO)

This breathing actress is so flawless that she was asked to present at the Young Hollywood Awards on August 2. The 21-year-old beauty presented former reality star Lauren Conrad with an award for her work with Blue Avocado, a site that features eco-friendly products for women.

Naturally these two had to snap a picture together after the award was presented, and they look like they could even be sisters! Kind of like this actress’s infamous on-screen half sister.

Not only do they both have flawless skin, winning smiles, and trendy bangs, but these ladies are both at the forefront of the fashion world. Can you guess who this actress is?
